Muhammad declared in Quran 31:29: "Don't you see that Allah merges night into day and he merges day into night and he has subjected the sun, and the moon each running its course for a term appointed...?".

But the movement of the sun and moon have nothing to do with day and night -- we get day and night because the earth is spinning!

Again in Quran 39:5, we read: "He makes the Night overlap the Day, and the Day overlap the Night: He has subjected the sun and the moon (to His law): Each one follows a course for a time appointed."

But the movement of the sun and moon have nothing to do with day and night -- we get day and night because the earth is spinning!

Finally, in Quran 36:40 it is stated: "It is not for the sun to overtake the moon, nor does the night outstrip the day. They float each in an orbit."

But the movement of the sun and moon have nothing to do with day and night -- we get day and night because the earth is spinning!

So Our Debate Question is then : Does the Quran (or anything else) indicate that Muhammad knew that the earth is spinning?
